ABSTRACT:
A dye image-receiving layer in a diffusion transfer image-receiving sheet comprises a novel mordant polymer which is a copolymer of 4-vinylpyridine, a monomer containing at least 2 ethylenically unsaturated groups and a monomer containing an .alpha.,.beta.-ethylenically unsaturated group. The polymer has excellent film-forming properties without the use of a solvent and does not require any film hardener.
